ELASTIC-FLUID TURBINE.

Specification of Letters Patent.

Patented Jan. 27,1914.

Application filed June 27. 1912. Serial No. 706.127.

To all whom it may concern Be it known that I. lVAL'ii-IR Kisser, a citizen of the Swiss Republic, residing at Charlottenburg. Germany. have invented certain new and useful Improvements in Elastic-Fluid Turbines, of which the following is a specification.

This invention relates to elastic fluid turbines. and its object is to produce a compact machine in which are combined two independent turbines. one of which is a high pressure engine supplying its exhaust steam to a heating or other industrial system, while the other is adapted to extract the energy of the steam fractionally in a plurality of stages connected to a condenser. ltoth turbines are mounted on a common shaft from which the combined power developed by both machines can be trans mitted to suitable driven mechanism. The

low pressure side of the tapped turbine is 1 connected not only to the heating or other the apparatus which I now consider to represent the best embodiment thereof; but I industrial system, but also to a low pres sure chamberof the condensing turbine, so

that the latter derives ;1 portion of its power from the exhaust steam of the former. By the combination of the two turbines in one casing a reduction in the length of the entire machine is obtained, and by reason of the absence of unnecessary walls and bearings the cost of manufacture considerably reduced.

lhe accompanying dranmg is a diagram- .natic sectionalrepresentation of a turbine l l l l l i l embodying the construction above set forth.

The high pressure turbine shown as consisting of but one bucket wheel 1 mounted on a shaft 2 and inclosed in a casing 3. A partitic-n 4 cuts off a portion of said casing to form a chamber for the wheel 1 which receives steam through one or more nozzles 5 located in said partition and communicating witi a chest or drum 6 which is connected with the live steam main 7. The remainder ofthe casing forms a chamber for the condensing turbine, which has a. plu rality of bucket wheels 8 all mounted on the shaft 2 and alternating with the diaphragms 9 which vsmoarate the several stages. The highest stage receives steam from the drum 6 through one or more nozzles 11. The lowest stage communicates by the exhaustpipe 10 with a condenser (not shown).

The admission of live steam to the two turbines may be effected otherwise than by means of the common drum 6. so as to afford opportunity for separate regulation of the two machines, if desired.

Preferably the greater portion of the exhaust from the high pressure turbine 1 flows oil through a pipe 12 to a heating or other industrial system. But the remainder of such exhaust escapes through a nozzle or nozzles 13 to a suitable stage of the condensing turbine. In the drawing. this nozzle is shown as lo ated in the partition between the two chambers of the casing, and delivering low pressure steam. to the first of the condensing turbine.

In accordance with the provisions of the patentstatutes. I have described the principle desire to have it understood that the apparatus shown is only illustrative, and that the invention can be'carried out by other means.

What I claim as new and desire to secure by Letters Patent of the l'nited States, is

1. The combination of a turbine casing, partition means dividing said easing into two chambers, a high pressure turbine in one chamber and a condensing turbine in the other chamber. a steam chest in theturbine casing with nozzles opening into both of the chambers for supplying steam to each of the turbines. there being also nozzles for discharging part of the exhaust steam from the high pressure turbine to a stagegof the condensing turbine, and outlet means from the high pressure turbine for diverting part of the exhaust steam therefrom to a heating or other industrial system.

2. The combination of a turbine casing. partition means dividing said casing into twochambers, a high pressure turbine in one chamber and a multi-stage condensing turbine in the other chamber mounted on a Q memes common shaft, a steam chest in the casing of the exhaust steam from the high pressure with nozzles at opposite sides thereof for turbine to a heating or similar system. 10
